Another Letter to EPA on the So-Called “Endangerment Finding”

I write in regard to the Proposed Endangerment and Cause or Contribute Findings for Greenhouse Gases Under Section 202(a) of the Clean Air Act, Proposed Rule, 74 Fed. Reg. 18,886 (Apr. 24, 2009), the so-called “Endangerment Finding.”

It has been often said that the “science is settled” on the issue of CO2 and climate. Let me put this claim to rest with a simple one-letter proof that it is false.
